Description of Feature or Work Requested

We've recently enabled ability to update the zones paramter on an existing scale set. Today, this can be set with the az vmss update --set or --update commands, like:

az vmss update --set zones=["1","2","3"] -n regionaltozonaluniform2 -g zoneexpansion

We'd like to simplify the ability to make this change on CLI with something like:

az vmss update --zones 1 2

@fitzgeraldsteele Due to the super busy schedule of this sprint, we didn't have the effort to develop this feature in this sprint. If this feature only adds a new parameter --zones without any breaking changes, could we schedule it for the next sprint (released at 07-02)?

July Sounds great. Thank you!
